Why Need Protocol Conversion Gateways?

Users can connect various on-site PLCs, sensors, and instruments from multiple vendors using multi-protocol conversion gateways, which employs ARM-based low-power processor and rich interfaces (RJ45, RS-485/232, Slot for SD Card and SIM card, USB, etc.), seamlessly converting protocols and connecting fieldshop equipment to the Internet for centralized machine-to-machine/ machine-to-cloud communication and management.

Installing protocol conversion gateways in your fieldshop is definitely a flexible and scalable means of achieving various protocol communication among isolated devices while avoiding extra time and money spent on redeveloping equipment and learning needed information.

Multiple Protocol Gateways for Selection

Dusun IoT protocol gateways are equipped with industrial data gathering and processing systems and a wide range of communication protocol libraries, and can communicate with equipment in the majority of industrial locations on the market today.

Protocol gateways collect field data via serial ports and Ethernet. After preliminary screening, calculation, and analysis, the data is forwarded to the local system based on the site’s actual application needs, or be forwarded to related cloud platforms via API/MQTT/WebSocket.

When the IIOT gateway has finished data collection, it will deliver data to the backend platforms. The gateway and platform must also agree on uplink data transferring protocols and data formats at this point. In general, there are two options: the gateway matches the platform’s protocol and data format, or the platform matches the gateway’s upload protocols and data format.

In terms of protocols, MQTT is widely supported by the majority of IoT platform currently on the market. Data can be uploaded/delivered once the protocol is defined. But if the data format (e.g. JSON) is not clearly defined, the uploaded data will be unable to appropriately parsed by the two ends. Therefore, after the MQTT protocol is defined, the data format between the gateway and the platform must be specified as well.

There are numerous industrial communication protocols for industrial automation. To allow machines to communicate with one another, each manufacturer develops its own proprietary communication protocol. However, when running industrial facilities like as dams, mines, power plants, and water treatment plants, a number of equipment from many different vendors engage in a single process to function, necessitating a high level of interoperability.

Protocol conversion gateways operate as intermediates between equipment that use multiple communication protocols, allowing these machines to interact with one another without being hindered by proprietary or legacy protocols. Simultaneously, equipment operating on open and private networks can be linked, facilitating communication between different systems.

Protocol gateways are classified into two categories, each with its specific functions: The first kind joins two networks that use different protocols. It can, for example, connect PROFIBUS to EtherNet I/P, allowing devices on these networks to interact with one another easily.

The second kind connects simpler devices, such as sensors, to more complex networks. This sort of protocol gateways often connect to the network via inbuilt serial ports, serving as translators between device protocols and network protocols.

Save Upgrade Cost

Protocol gateways allow devices that use various protocols to interact and collaborate without the need for costly hardware or software upgrades.

Add Value of Legacy Equipment

Protocol gateways allow legacy devices to connect with modern devices and networks, extending their useful life.

Reduce Network Implementation Cost

Protocol gateways allow factories to reduce cost on replacement of the entire system, continue to use existing I/O modules and wire infrastructure, minimising disturbance to the production process simultaneously.

Easy and Cost-effective

Protocol gateways connect devices from various manufacturers, allowing the expansion of PLC systems. This enables enterprises to select the device that best matches their application rather than being constrained to what a single vendor has to offer.

Future Proofness

Protocol gateways allows businesses to keep their systems up to date and readily adjust to changing demands. This forward-thinking attitude allows firms to stay competitive and efficient in a rapidly changing environment.
